ICE-HOUSE, ICE-BOX,

AND REFRIGERATOR.

SPEQIFIGATION forming part of Letters Fatent No. 244,374, dated July 19, 1881.

' Application filed March 17, 1880. (ModeL) To all whom it may concern:

Be it known that I, J USTUS BRAUER, a citizen of the United States, residing in the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in lee-Houses, Ice-Boxes, and Refrigerators,which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to improvements in icehouses, ice-boxes, refrigerators, and other re ceptacles in which articles are to'be preserved or cooled by cooling the air, and the object is to construct receptacles of this kind in such manner that the articles contained or to be stored therein will. remain fresh and will not spoil, while beer and malt liquors are kept under a more regular and even temperature than in ice-houses as now ordinarily constructed. At the same time, by having an even temperature, a large quantity of ice, especially in large ice-houses, can besaved,while in those as now constructed the temperature is not uniform, and has to be forced at the expense of large quantities of ice. v

The invention consists, principally, in em ployin g granulated cork, so closely packed as to form almost a solid mass between the walls or sides and top and bottom, and in such manner that the inner and outer walls thereof are preferably entirely isolated from each other by cork packed around'the uprights.

It also consists of a peculiar open drip-floor, so that the condense water will be guided to suitable gutters, from which it is carried off in any suitable manner. The drip-floor can be made to conform to any shape, either arch, incline, hip, or other formed roof or ceiling. The foul air, evaporation, and stench caused by meats and similar articles can freely ascend between the spaces formed between the slats or ledges of the drip-floor, whilethe cold air from the ice on the grated floor above can pass freely down and assist in always maintaining an even and regular temperature.

It also consists in the construction and arrangement of certain parts, as will be more definitely described hereinafter, reference being had to the accompanying drawings, in which- Figure 1 is a horizontal section on line w a;

"is of peculiar construction.

of Fig. 4. of an ice-house. Fig. 2 is a vertical central cross-section of the same. Fig. 3 is a horizontal section on line y y. Fig. 4 is a vertical central cross section atright angles to Fig. 2., Fig. 5 is a plan and section of one of the ledges. Figs. 6 and 7 are diagrams of the modified arrangements of the drip-floor.

In the drawings, A and B are the inner and outer walls of an ice-house, between which an air space is formed. On the inside of the wall B is arranged a lining, O,'pr,operly supported by uprights G and cross-pieces O. The space between this lining O and wall B is packed with very closely-rammed granulated cork of nearly uniform particles, and to form nearly a solid mass. It is very important that the proper quantity and thickness of cork be applied in ice-houses, and I have ascertainedby actual experience that about four inches will withstand any degree of heat from penetrating through the walls. In the upper part of the ice-house or refrigerator is arranged the grated floor D,upon which the ice is supported, and around the iioorD is secured to the wall B an inclined ledge, 01, by which all drip-water is conducted away from the wall 0, and thereby prevents the.wood-work of the wall from rotting. The water falls upon the drip-floor E, which It consists of ledges or slats F, which are constructed of boards b, Fig. 5, covered with galvanized or other suitable metal, 0, bent over one of the edges, as shown at e. The boards I) are recessed at one side, as shown at g, to prevent any drip-water from lumps of ice which might lodge at that side frombeing drawn against the ledge-boards by capillary attraction. At... the opposite side of the ledge are formed gutters, f, for conducting the drip-water to the lowest corner of the ledges, which forms a tongue or point, 'i, fromwhieh all the drip-water drops off into the gutters'below, as shown in Figs. 2 and 4. The girders may however be cut in any other desired manner for supporting the ledges, and to suit different-shaped ceilings or roofs, examples of which are shown in Figs. 6 and 7 Under the drip-floor E is secured in any suitable Inanner one or more gutters, H, slightly inclined, and having an utlet-spout, 10, through which the water can pass to any desired place or receptacle.

By arranging the ledges in the manner shown,

they can be easily cleaned from below of sawdust, slime, &c., and replaced in position. The cold air can freely circulate between the overhanging sides of the ledges, and all foul odors are oviated, especially in butchering or similar establishments.

The walls may be built of brick, stone, or other material when building an ice-house, and, if desired, the air-space may be extended in the roof or ceiling.

I am aware that granulated cork loosely applied between the walls of refrigerators has been employed; but this has been found to be impracticable, and no better than sawdust and similar articles, and only by a long series of experiments have I discovered that to practically employ granulated cork in ice-houses, &c., it must be closely packed, and to do this properly the cork should be of a nearly-uniform size of particles, prepared to pack closely, so as to form a nearly solid mass.

Having thus described my invention, what 1 claim is 1. In an ice-house or refrigerator having an air-space between its inner and outer walls, A B, a lining, G, forming a space to be filled with closely-packed granulated cork of nearly-uniform size, substantially as specified.

2. An ice-house or refrigeratorconsisting of innerandouterwalls,AB,formingan air-space, and alining, O, forming aspace to be filled with closely-packed granulated cork, a grated floor, and a drip-floor, constructed substantially as shown and specified.

3. In an ice'honse or refrigerator having inner and outer walls, forming an air-space, and a supplementary space packed with closelyrammed granulated cork, the inclined ledge (1, arranged as shown, and for the purpose herein specified.

4. In an ice-house or refrigerator provided with an air-space between its inner and outer walls, and having a supplementary space packed with closely-rammed granulated cork, a drip-floor consisting of girders supporting removable ledges provided with gutters f, overhanging edges e,'and recesses g, constructed substantially as shown and specified.

5. In an ice-house or refrigerator having inner and outer walls, formingan air-space, an inner space packed with closely-rammed granulated cork, a drip-floor constructed as described, and gutters for carrying off the dripwater, all arranged substantially as shown and specified.

6. The ice-house herein described, having inner and outer walls, A 13, forming an air-space, linin gC,formin gasupplementary space packed with closely-granulated cork, a grating, D, inclined ledge d, drip-floor E, provided with removable ledges F, and gutter H, all constructed and arranged as shown and specified.

7. Anice-househavinginnerandouterwalls, A B, formingan air-space, and alinin g, (J, formin g a space packed with closely-rammed granulated cork, in combination with a grated floor, D, inclined ledge d, drip-floor E, constructed substantially as described, and suitable gutters for carrying off the drip-water, all substantially as specified.

8. An ice-house, refrigerator, 850., having inner and outer walls, AB, forming an air-space, with an inner lining, 0, the space between which and wall B is filled with granulated cork ot' nearly-uniform size, and packed by ramming, to form a compact mass, substantially as herein specified.
